New Swarm Controllers

I’ve ordered the second version of the swarm control boards. If you want some, you can get them here, but I advise against doing so until after a post shows up here saying either that they work, or that they’re busted.

In the mean time, I’ve been realizing that the boards are good for all sorts of stupid tricks. For instance, you can control people using galvanic vestibular stimulation, which uses 1-1.5mA at pretty low voltages (More academic version, more hacking). Since the swarm control boards already use a 3.7v lithium cell, additional voltage regulation isn’t needed (if anything, they may be too weak), and PWM can be used to control the current. A resistor in series might also be good, in case of… errors.

The same board could also be connected to a door latch, or magnetic strike, which would let a user connect to a web page (the ESP8266 can serve web pages and act as an AP) and put in a password to open the door. Lockitron appears to be making a business out of selling this, but the mechanics are cheaper.

Given that there’s also an I2C bus on the device, IO expanders, sensors, and other goofiness could be added to make wearables that respond to the environment, smart dust sensors, IoT nodes for home automation, scales that tweet about how much you weigh, etc. IoT is the new black! It’s a floor wax! It’s a dessert topping!
